i have tried using other version of itext but they are showing problem of ligature in indic languages

import org.apache.poi.xwpf.converter.pdf.PdfConverter;

import org.apache.poi.xwpf.converter.pdf.PdfOptions;

import org.apache.poi.xwpf.usermodel.XWPFDocument;

import org.springframework.util.FileCopyUtils;
import java.io.*;

public class Docx2PdfConverterUsingPOI implements Docx2PdfConverter{
    public byte[] convert(byte[] docxData) {

        byte[] output = null;
        try {
            InputStream isFromFirstData = new ByteArrayInputStream(docxData);

            XWPFDocument document = new XWPFDocument(isFromFirstData);
            PdfOptions pdfOptions = PdfOptions.create();
            // pdfOptions.fontEncoding(BaseFont.IDENTITY_H);
            //make new file in c:\temp\
            ByteArrayOutputStream out = new ByteArrayOutputStream();
            //Options options =


            Options.getTo(ConverterTypeTo.PDF).via(ConverterTypeVia.XWPF).
            subOptions(pdfOptions);
            PdfConverter.getInstance().convert(document, out, pdfOptions);






            document.close();
            return out.toByteArray();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return output;

    }

    public static void main(String args[]){
        Docx2PdfConverterUsingPOI docx2PdfConverterUsingPOI =new

        Docx2PdfConverterUsingPOI();

        String inputFile = "D:\\WORKSPACE\\yogesh\\letters\\out.docx";

        FileInputStream inputStream = null;
        try {

            inputStream = new FileInputStream(new File(inputFile));
            byte[]output =





            docx2PdfConverterUsingPOI.convert(FileCopyUtils.
            copyToByteArray(inputStream));
            FileCopyUtils.copy(output,new
            File("D:\\WORKSPACE\\yogesh\\letters\\out1.pdf"));

            } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

  • See https://stackoverflow.com/questions/51440312/docx-to-pdf-converter-in-java -- the PdfConverter you are using is out of date – PJ Fanning Aug 23 '19 at 23:13
  • the new version still uses itext 2.1.7. I want to use itext 7(pdfcalligraph on) with it because it solves my indic language problem. – Choupane Pushkar Jayant Aug 24 '19 at 07:22

    itext 7 has licensing that discourages its use - you would probably need a commercial license to use it - it should be feasible to fork the opensagres code to work with itext 7 if that's what you want - if you are forking the opensages code, maybe you could use https://en.wikipedia.org/wiki/OpenPDF or https://pdfbox.apache.org/ instead – PJ Fanning Aug 24 '19 at 11:36

    You are using pdfCalligraph, which is a commercial add-on of iText, which means that you have a support contract. Please contact iText Software directly for technical support. – Amedee Van Gasse Aug 26 '19 at 10:06
